Summary

Percutaneous discectomy for lumbar disc herniation showed limited success, with over half of patients experiencing persistent symptoms or requiring further surgery. Surgical discectomy proved more predictable and successful for treating lumbar disc herniation.

Area of Science:

  • Neurosurgery
  • Orthopedic Surgery
  • Minimally Invasive Procedures

Background:

  • Lumbar disc herniation is a common condition causing significant pain and disability.
  • Percutaneous discectomy is a minimally invasive technique offered as an alternative to traditional surgery.
  • Evaluating the efficacy of percutaneous discectomy compared to surgical discectomy is crucial for patient management.

Purpose of the Study:

  • To assess the outcomes of percutaneous discectomy for single-level unilateral lumbar disc herniation (L4-L5 or L5-S1).
  • To compare the success rates and complication profiles of percutaneous discectomy versus surgical discectomy.
  • To determine the long-term effectiveness and patient return-to-work rates following percutaneous discectomy.

Main Methods:

  • A cohort of patients with confirmed lumbar disc herniation underwent percutaneous discectomy.

  • Imaging modalities included computed tomographic (CT) scans, myelograms, and magnetic resonance imaging (MRI).
  • Patient outcomes were evaluated based on symptom resolution, return to work, and need for subsequent surgical intervention, with an average follow-up of 16.8 months.

    • Main Results:

    • Only 55% of patients returned to work after percutaneous discectomy.
    • 13 patients required subsequent surgical discectomy due to persistent symptoms.
    • Patients not undergoing surgical discectomy experienced significantly more pain, weakness, and numbness compared to those who did.

    Conclusions:

    • Percutaneous discectomy demonstrates lower predictability and success rates compared to surgical discectomy for lumbar disc herniation.
    • A significant proportion of patients undergoing percutaneous discectomy experience residual symptoms or require further surgical treatment.
    • Surgical discectomy appears to be a more reliable treatment option for managing lumbar disc herniation.
